A nurse is collecting data from a client about range-of-motion for various joints. Which of the following should the nurse identify as an example of a ball and socket joint?

A. "Your baby needs to suck on a pacifier" is not necessarily the best advice for this situation. While pacifiers can help some babies self-soothe, crying is often a sign of an unmet need, and further assessment is needed to determine the cause of the crying. Offering a pacifier without addressing other potential causes might overlook the root issue.

B. "Swaddling your baby snugly in a blanket might help soothe her" is correct. Swaddling can help calm a newborn by providing a sense of security and warmth, mimicking the conditions of the womb. It is a common technique used to soothe babies.

C. "Breastfed babies are usually fussy from swallowing too much air during feedings" is incorrect. While some babies may have mild gas or discomfort from swallowing air, excessive crying is not typically due to this alone, especially if the baby has been fed properly and burped.

D. "Breastfed babies often need to be supplemented with formula" is not appropriate. While some breastfeeding difficulties can occur, advising formula supplementation without further investigation could undermine the breastfeeding process and should only be suggested after careful assessment and if truly necessary.

A. A negative pressure room is correct. Varicella zoster, which causes chickenpox, is an airborne virus. Therefore, airborne precautions are required, which include placing the client in a negative pressure room to prevent the spread of the virus to other areas of the facility.

B. Administering aspirin is incorrect. Aspirin should not be given to children or adolescents with varicella zoster due to the risk of Reye's syndrome. Instead, an antipyretic such as acetaminophen should be used to treat fever.

C. Contact precautions are not sufficient for varicella zoster, as the virus requires airborne precautions to prevent transmission through the air.

D. Having visitors remain at least 0.91 m (3 feet) away is incorrect. Airborne precautions require that visitors wear appropriate PPE, including respirators, and should not be restricted to 3 feet away. Ideally, visitors should wear full protective gear when entering the room.
